Forging wheel hub is a production process of wheel hub. Precision technology, high strength and light weight. The forging process is complex, so the manufacturing cost is high. Forged wheels are generally used for high-grade cars, and cast wheels are used for ordinary cars. The manufacturing process of the forged wheel hub is: first heat the aluminum block to a certain temperature, then press it into a blank with a forging press, and then spin the blank into shape. After this process, its molecular structure will become very tight and can withstand higher pressure. The forged hub is made of military-grade aluminum, which is lighter in weight. Forged hub can also be subdivided into single forging and multi-piece forging. One-piece forging means that the whole wheel hub is formed in one, with light weight and good reliability. The multi-piece forged rim is separated from the spoke rim. The advantage of this structure is that new hub styles can be obtained by replacing spokes. Compared with single forging, multi-piece forging is heavier and requires higher assembly requirements.
We focus on providing lightweight solutions for human travel, providing customers with more environmentally friendly, safer and lighter products, and developing various products for application in the fields of automobile, rail transit, F1 racing, satellite and so on. By supporting many customers in Europe, North America, Japan and independent brands, CITIC Yu Bingxuan has a deep understanding of the design needs, technical standards and development process systems of different customers around the world, and can provide customers with fast “integrated solutions”, and provide customers with a variety of creative solutions from the conceptual stage.
Technical advantages of spinning hub
Spinning is a technology that produces plastic molding by rotary force calendering. In the process of plastic forming, the billet is repeatedly squeezed by strong force, which makes the crystal structure inside the aluminum alloy more compact and the molecular structure is fibrous, thus strengthening the key mechanical properties of the aluminum alloy material such as yield strength, tensile strength, elongation, etc., so that the aluminum alloy material can reach a better mechanical state, and finally realize the lightweight and durability of the wheel hub by combining the structural optimization.
The inclined casting technology is adopted for the hub blank, which can realize rapid cooling and make the molecular structure of the hub blank more compact. At the same time, in the cooling process, the potential energy of equipment turnover is used to increase the cooling of molten aluminum under heavy pressure, further improving the mechanical properties of the spoke.
The blank is plastic formed under the action of spinning pressure, which makes the crystal structure more compact and fibrous, and the mechanical properties of the material are stronger and the strength is further improved, so as to achieve lighter weight and higher
